We need to try moving the Lago slaves in CI to work with memory instead of local disks,
It might speed up the tests significantly.
We have 2 choices:
1. add code to the job and mount the dir on /dev/shm/
2. create zram drive and mount the following dirs on it:
Each host should have enough memory to run current tests on them,
however we'll need to make sure to clean that drive after each run.
Lets try it on one of the slaves to see what is the best solution before implementing for all slaves.
